Risk Overview

Overall natural disaster risk in Kent County is low, with a National Risk Index score of 69.4 out of 100 — placing it in the 69th national percentile and below the national average for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.

Risk here concentrates in hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Medium risk — $3M in expected annual loss and about 0.18 events per year; riverine flood (rivers and streams overflowing their banks after heavy rain or snowmelt) at Medium risk — $23M in expected annual loss and about 1.39 events per year; and earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $1M in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $32M in expected annual loss for a population of 170K.

Beyond physical exposure, Kent County has a low social vulnerability rating (how susceptible the population is to harm) and a very high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.

History supports the rating: Kent County has received 23 federal disaster declarations since 1978, including 8 for hurricane events and 6 for severe storm events. The most recent was Severe Storms and Flooding (severe storm), declared in March 2024.

Among 5 Rhode Island counties, Kent County ranks #2 for overall natural disaster risk.
